What is the difference between mmol/l and mg/dl?
Both sets of units are used to test blood sugar levels and provide a measurement of the amount of glucose in the blood.
– The most used unit of measurement in the UK is mmol/l (millimoles per litre), which is the worldwide standard unit for measuring the concentration of glucose in the blood
– In the USA and continental Europe, mg/dl (Milligrams per 100 millilitres) is used.
